Summary: The patch adds support for BlobDB to `db_stress`. Note that BlobDB currently does not support (amongst other features) Column Families or the `SingleDelete` API, so for now, those should be disabled on the command line when running `db_stress` in BlobDB mode (using `-column_families=1` and `-nooverwritepercent=0`, respectively). Also, some BlobDB features that do not go well with the verification logic in `db_stress` like TTL and FIFO eviction are not supported currently.

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage
RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)
This code is a library that forms the core building block for a fast key-value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it especially suitable for storing multiple terabytes of data in a single database.
